I have mixed feelings about Nirvana seed, good smoke but a poor germination rate last time(20%). I too love a good Blueberry and will run the other 4 seeds in 3 gallon after finishing up the autos I'm running now, so I should be able to put this to rest.
I think the air pot is going to kick ass as long as I can keep it watered property, this is a good time for high frequency watering.
We shall see.
